Method Summary

Modifier and Type	Method and Description
void	checkContent(CompilerService compiler, Expression expression) Compile code to check the content of the node, and adjust it if necessary On entry the proposed content is on the stack as a CharSequence; on exit the revised content must be on the stack as a CharSequence.
protected void	compileNodeName(CompilerService compiler, Expression expression) Compile code to generate the node name (if any) and leave it on the top of the stack.
protected boolean	isNamedNodeKind() Ask whether this instruction generates a kind of node that is named
protected void	pushNode(CompilerService compiler, Expression expression) Generate code to write the node to the current receiver.

Method Detail

isNamedNodeKind

protected boolean isNamedNodeKind()

Ask whether this instruction generates a kind of node that is named

Overrides:

isNamedNodeKind in class SimpleNodeConstructorCompiler

compileNodeName

protected void compileNodeName(CompilerService compiler,
                               Expression expression)
                        throws CannotCompileException

Compile code to generate the node name (if any) and leave it on the top of the stack. For node kinds that are always unnamed (such as comments), the stack is not changed. For node kinds that may be named or unnamed (namespace nodes), an entry is always added to the stack, which will be null if the particular node has no name.

Overrides:

compileNodeName in class SimpleNodeConstructorCompiler

Throws:

CannotCompileException

checkContent

public void checkContent(CompilerService compiler,
                         Expression expression)

Description copied from class: SimpleNodeConstructorCompiler

Compile code to check the content of the node, and adjust it if necessary On entry the proposed content is on the stack as a CharSequence; on exit the revised content must be on the stack as a CharSequence.

Overrides:

checkContent in class SimpleNodeConstructorCompiler

pushNode

protected void pushNode(CompilerService compiler,
                        Expression expression)

Generate code to write the node to the current receiver. On entry the stack holds the current receiver, the node name (for named node kinds only) and the content (for all nodes)

Specified by:

pushNode in class SimpleNodeConstructorCompiler

Parameters:

compiler -

expression -
