Constructor Detail

VMArrayInitializer

public VMArrayInitializer()

Constructor, creates a new VMArrayInitializer for use in the virtual machine.

VMArrayInitializer

public VMArrayInitializer(java.lang.String file,
                          int line)

Constructor, creates a new VMArrayInitializer instance which is located as Brahms source code in the given file at the given line number.

Parameters:

file - the name of the file

line - the line number in the file

VMArrayInitializer

public VMArrayInitializer(JavaType type,
                          java.lang.String file,
                          int line)

Constructor, creates a new VMArrayInitializer operation which is located as Brahms source code in the given file at the given line number.

Parameters:

type - the JavaType representing the Java array class to be created

file - the name of the file

line - the line number in the file

Method Detail

evaluate

public java.util.List<java.lang.Object> evaluate(VMActiveInstanceCtx agent,
                                                 VMFrameCtx frame)
                                          throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Evaluates the array initializer expression to produce a new array. A singleton list of the new array is returned to conform to the contract for the evaluate method.

Specified by:

evaluate in interface IVMExpression

Parameters:

agent - the VMActiveInstanceCtx for the agent performing the expression evaluation

frame - the VMFrameCtx for the frame that is being executed -- contains variable contexts for variables used in the evaluation

Returns:

List<Object> a singleton list containing the array resulting from the expression evaluation

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if an error occurs during the expression evaluation
