Locator

public Locator(Parser parser)

Creates a locator for the given parser.

参数:

parser - The parser with the Page being accessed.

方法详细资料

getPublicId

public java.lang.String getPublicId()

Return the public identifier for the current document event.

The return value is the public identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

指定者:

getPublicId 在接口中 org.xml.sax.Locator

返回:

A string containing the public identifier, or null if none is available.

另请参阅:

getSystemId()

getSystemId

public java.lang.String getSystemId()

Return the system identifier for the current document event.

The return value is the system identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application. For example, a file name must always be provided as a file:... URL, and other kinds of relative URI are also resolved against their bases.

指定者:

getSystemId 在接口中 org.xml.sax.Locator

返回:

A string containing the system identifier, or null if none is available.

getPublicId()

getLineNumber

public int getLineNumber()

Return the line number where the current document event ends. Lines are delimited by line ends, which are defined in the XML specification.

Warning: The return value from the method is intended only as an approximation for the sake of diagnostics; it is not intended to provide sufficient information to edit the character content of the original XML document. In some cases, these "line" numbers match what would be displayed as columns, and in others they may not match the source text due to internal entity expansion.

The return value is an approximation of the line number in the document entity or external parsed entity where the markup triggering the event appears.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event. The first line is line 1.

指定者:

getLineNumber 在接口中 org.xml.sax.Locator

返回:

The line number, or -1 if none is available.

getColumnNumber()

getColumnNumber

public int getColumnNumber()

Return the column number where the current document event ends. This is one-based number of Java char values since the last line end.

Warning: The return value from the method is intended only as an approximation for the sake of diagnostics; it is not intended to provide sufficient information to edit the character content of the original XML document. For example, when lines contain combining character sequences, wide characters, surrogate pairs, or bi-directional text, the value may not correspond to the column in a text editor's display.

The return value is an approximation of the column number in the document entity or external parsed entity where the markup triggering the event appears.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event. The first column in each line is column 1.

指定者:

getColumnNumber 在接口中 org.xml.sax.Locator

返回:

The column number, or -1 if none is available.
