构造器

构造器和说明
DocType(java.lang.String elementName) This will create the DocType with the specified element name
DocType(java.lang.String elementName, java.lang.String systemID) This will create the DocType with the specified element name and reference to an external DTD.
DocType(java.lang.String elementName, java.lang.String publicID, java.lang.String systemID) This will create the DocType with the specified element name and a reference to an external DTD.

方法概要

限定符和类型	方法和说明
DocType	clone() Return a deep clone of this instance.
DocType	detach() Detaches this child from its parent or does nothing if the child has no parent.
java.lang.String	getElementName() This will retrieve the element name being constrained.
java.lang.String	getInternalSubset() This returns the data for the internal subset.
Document	getParent() Return this child's parent, or null if this child is currently not attached.
java.lang.String	getPublicID() This will retrieve the public ID of an externally referenced DTD, or an empty String if none is referenced.
java.lang.String	getSystemID() This will retrieve the system ID of an externally referenced DTD, or an empty String if none is referenced.
java.lang.String	getValue() Returns the empty string since doctypes don't have an XPath 1.0 string value.
DocType	setElementName(java.lang.String elementName) This will set the root element name declared by this DOCTYPE declaration.
void	setInternalSubset(java.lang.String newData) This sets the data for the internal subset.
DocType	setPublicID(java.lang.String publicID) This will set the public ID of an externally referenced DTD.
DocType	setSystemID(java.lang.String systemID) This will set the system ID of an externally referenced DTD.

DocType

public DocType(java.lang.String elementName,
               java.lang.String publicID,
               java.lang.String systemID)

This will create the DocType with the specified element name and a reference to an external DTD.

参数:

elementName - String name of element being constrained.

publicID - String public ID of referenced DTD

systemID - String system ID of referenced DTD

抛出:

IllegalDataException - if the given system ID is not a legal system literal or the public ID is not a legal public ID.

IllegalNameException - if the given root element name is not a legal XML element name.

DocType

public DocType(java.lang.String elementName,
               java.lang.String systemID)

This will create the DocType with the specified element name and reference to an external DTD.

参数:

elementName - String name of element being constrained.

systemID - String system ID of referenced DTD

抛出:

IllegalDataException - if the given system ID is not a legal system literal.

IllegalNameException - if the given root element name is not a legal XML element name.

DocType

public DocType(java.lang.String elementName)

This will create the DocType with the specified element name

参数:

elementName - String name of element being constrained.

抛出:

IllegalNameException - if the given root element name is not a legal XML element name.

方法详细资料

getElementName

public java.lang.String getElementName()

This will retrieve the element name being constrained.

返回:

String - element name for DOCTYPE

setElementName

public DocType setElementName(java.lang.String elementName)

This will set the root element name declared by this DOCTYPE declaration.

参数:

elementName - String name of root element being constrained.

返回:

this DocType instance

抛出:

IllegalNameException - if the given root element name is not a legal XML element name.

getPublicID

public java.lang.String getPublicID()

This will retrieve the public ID of an externally referenced DTD, or an empty String if none is referenced.

返回:

String - public ID of referenced DTD.

setPublicID

public DocType setPublicID(java.lang.String publicID)

This will set the public ID of an externally referenced DTD.

参数:

publicID - id to set

返回:

DocType DocType this DocType object

抛出:

IllegalDataException - if the given public ID is not a legal public ID.

getSystemID

public java.lang.String getSystemID()

This will retrieve the system ID of an externally referenced DTD, or an empty String if none is referenced.

返回:

String - system ID of referenced DTD.

setSystemID

public DocType setSystemID(java.lang.String systemID)

This will set the system ID of an externally referenced DTD.

参数:

systemID - id to set

返回:

systemID String system ID of referenced DTD.

抛出:

IllegalDataException - if the given system ID is not a legal system literal.

getValue

public java.lang.String getValue()

Returns the empty string since doctypes don't have an XPath 1.0 string value.

指定者:

getValue 在类中 Content

返回:

the empty string

setInternalSubset

public void setInternalSubset(java.lang.String newData)

This sets the data for the internal subset.

参数:

newData - data for the internal subset, as a String.

getInternalSubset

public java.lang.String getInternalSubset()

This returns the data for the internal subset.

返回:

String - the internal subset

toString

public java.lang.String toString()

This returns a String representation of the DocType, suitable for debugging.

覆盖:

toString 在类中 java.lang.Object

返回:

String - information about the DocType

clone

public DocType clone()

Return a deep clone of this instance. Even if this instance has a parent, the returned clone will not.

All JDOM core classes are Cloneable, and never throw CloneNotSupportedException. Additionally all Cloneable JDOM classes return the correct type of instance from this method and there is no need to cast the result (co-variant return vaue).

Subclasses of this should still call super.clone() in their clone method.

覆盖:

clone 在类中 Content

detach

public DocType detach()

从类复制的说明: Content

Detaches this child from its parent or does nothing if the child has no parent.

This method can be overridden by particular Content subclasses to return a specific type of Content (co-variant return type). All overriding subclasses must call super.detach();

覆盖:

detach 在类中 Content

返回:

this child detached

getParent

public Document getParent()

从类复制的说明: Content

Return this child's parent, or null if this child is currently not attached. The parent can be either an Element or a Document.

This method can be overridden by particular Content subclasses to return a specific type of Parent (co-variant return type). All overriding subclasses must call super.getParent();

覆盖:

getParent 在类中 Content

返回:

this child's parent or null if none
