Method Detail

assumeFunction

public boolean assumeFunction()

Description copied from interface: FunctionCalls.CallInfo

Assumes that a function is called.

Specified by:

assumeFunction in interface FunctionCalls.CallInfo

getArg

public Value getArg(int i)

Description copied from interface: FunctionCalls.CallInfo

Returns the value of the i'th argument. The first argument is number 0. Returns 'absent' if the argument is not provided. Can be used even if the number of arguments is unknown.

Specified by:

getArg in interface FunctionCalls.CallInfo

See Also:

FunctionCalls.CallInfo.getUnknownArg()

getExecutionContext

public ExecutionContext getExecutionContext()

Description copied from interface: FunctionCalls.CallInfo

Returns the execution context.

Specified by:

getExecutionContext in interface FunctionCalls.CallInfo

getFunctionValue

public Value getFunctionValue()

Description copied from interface: FunctionCalls.CallInfo

Returns the abstract value describing which function to call.

Specified by:

getFunctionValue in interface FunctionCalls.CallInfo

getJSSourceNode

public AbstractNode getJSSourceNode()

Description copied from interface: FunctionCalls.CallInfo

Returns the node in the JavaScript code where this call originates from. This is different from the ordinary source node for calls inside host functions.

Specified by:

getJSSourceNode in interface FunctionCalls.CallInfo

getNumberOfArgs

public int getNumberOfArgs()

Description copied from interface: FunctionCalls.CallInfo

Returns the number of arguments.

Specified by:

getNumberOfArgs in interface FunctionCalls.CallInfo

See Also:

FunctionCalls.CallInfo.isUnknownNumberOfArgs()

getResultRegister

public int getResultRegister()

Description copied from interface: FunctionCalls.CallInfo

Returns the result register.

Specified by:

getResultRegister in interface FunctionCalls.CallInfo

getSourceNode

public AbstractNode getSourceNode()

Description copied from interface: FunctionCalls.CallInfo

Returns the node where the call originates from. Note that this may be an indirect call via call/apply.

Specified by:

getSourceNode in interface FunctionCalls.CallInfo

getThis

public Value getThis()

Description copied from interface: FunctionCalls.CallInfo

Returns the value of 'this'.

Specified by:

getThis in interface FunctionCalls.CallInfo

getUnknownArg

public Value getUnknownArg()

Description copied from interface: FunctionCalls.CallInfo

Returns the value of an unknown argument. Only to be called if the number of arguments is unknown. Always includes 'undefined' (not 'absent').

Specified by:

getUnknownArg in interface FunctionCalls.CallInfo

isConstructorCall

public boolean isConstructorCall()

Description copied from interface: FunctionCalls.CallInfo

Checks whether this is a constructor call or an ordinary call.

Specified by:

isConstructorCall in interface FunctionCalls.CallInfo

isUnknownNumberOfArgs

public boolean isUnknownNumberOfArgs()

Description copied from interface: FunctionCalls.CallInfo

Returns true if the number of arguments is unknown.

Specified by:

isUnknownNumberOfArgs in interface FunctionCalls.CallInfo
