public Text(String text)

Create text syntax tree node.

Parameters
text:String

Method Detail

canLoadAsArrayOffsetLengthback to summary
public boolean canLoadAsArrayOffsetLength()

Check whether this Text node can be stored in a char[] in the translet. Calling this is precondition to calling loadAsArrayOffsetLength.

Returns:boolean

protected boolean contextDependent()

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.contextDependent.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.contextDependent.

Returns true if this expression/instruction depends on the context. By default, every expression/instruction depends on the context unless it overrides this method. Currently used to determine if result trees are compiled using procedures or little DOMs (result tree fragments).

displayback to summary
public void display(int indent)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.display.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.display.

Displays the contents of this syntax tree node (to stdout). This method is intended for debugging _only_, and should be overridden by all syntax tree node implementations.

getTextback to summary
protected String getText()

Returns the text wrapped inside this node

Returns:String

The text wrapped inside this node

isWhitespaceback to summary
private static boolean isWhitespace(char c)
loadAsArrayOffsetLengthback to summary
public void loadAsArrayOffsetLength(ClassGenerator classGen, MethodGenerator methodGen)

Generates code that loads the array that will contain the character data represented by this Text node, followed by the offset of the data from the start of the array, and then the length of the data. The pre-condition to calling this method is that canLoadAsArrayOffsetLength() returns true.

parseContentsback to summary
public void parseContents(Parser parser)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.parseContents.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.parseContents.

Parse the contents of this syntax tree nodes (child nodes, XPath expressions, patterns and functions). The default behaviour is to parser the syntax tree node's children (since there are no common expressions, patterns, etc. that can be handled in this base class.

setTextback to summary
protected void setText(String text)

Set the text for this node. Appends the given text to any already existing text (using string concatenation, so use only when needed).

Parameters
text:String

is the text to wrap inside this node.

translateback to summary
public void translate(ClassGenerator classGen, MethodGenerator methodGen)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Instruction.translate.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Instruction.translate.

Translate this node into JVM bytecodes.
