public class Text
extends Content

An XML character sequence. Provides a modular, parentable method of representing text. Text makes no guarantees about the underlying textual representation of character data, but does expose that data as a Java String.

构造器详细资料

Text

public Text(java.lang.String str)

This constructor creates a new Text node, with the supplied string value as it's character content.

参数:

str - the node's character content.

抛出:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

方法详细资料

getText

public java.lang.String getText()

This returns the value of this Text node as a Java String.

返回:

String - character content of this node.

getTextTrim

public java.lang.String getTextTrim()

This returns the textual content with all surrounding whitespace removed. If only whitespace exists, the empty string is returned.

返回:

trimmed text content or empty string

getTextNormalize

public java.lang.String getTextNormalize()

This returns the textual content with all surrounding whitespace removed and internal whitespace normalized to a single space. If only whitespace exists, the empty string is returned.

返回:

normalized text content or empty string

normalizeString

public static java.lang.String normalizeString(java.lang.String str)

This returns a new string with all surrounding whitespace removed and internal whitespace normalized to a single space. If only whitespace exists, the empty string is returned.

Per XML 1.0 Production 3 whitespace includes: #x20, #x9, #xD, #xA

参数:

str - string to be normalized.

返回:

normalized string or empty string

setText

public Text setText(java.lang.String str)

This will set the value of this Text node.

参数:

str - value for node's content.

返回:

the object on which the method was invoked

抛出:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

append

public void append(java.lang.String str)

This will append character content to whatever content already exists within this Text node.

参数:

str - character content to append.

抛出:

IllegalDataException - if str contains an illegal character such as a vertical tab (as determined by Verifier.checkCharacterData(java.lang.String))

append

public void append(Text text)

This will append the content of another Text node to this node.

参数:

text - Text node to append.

getValue

public java.lang.String getValue()

Returns the XPath 1.0 string value of this element, which is the text itself.

指定者:

getValue 在类中 Content

返回:

the text

toString

public java.lang.String toString()

This returns a String representation of the Text node, suitable for debugging. If the XML representation of the Text node is desired, either getText() or XMLOutputter.outputString(Text) should be used.

覆盖:

toString 在类中 java.lang.Object

返回:

String - information about this node.

clone

public Text 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 Text 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 Element 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
