ASTIdentifier

public ASTIdentifier(int id)

Create the node given an id.

Parameters: id node id.

ASTIdentifier

Method Detail

execute

public Object execute(Object obj, JexlContext jc)

returns the value of itself applied to the object. We assume that an identifier can be gotten via a get(String). e.g. if we have bean.property, 'property' has been parsed as an identifier, and we need to resolve the expression by calling the property getter.

Parameters: obj the object to evaluate against. jc the JexlContext.

Returns: the resulting value.

Throws: Exception on any error.

getIdentifierString

public String getIdentifierString()

Gets the name of the variable.

Returns: the variable name.
