Constructor Detail

InvokeDynamicInfo

public InvokeDynamicInfo(int bootstrapMethodIndex,
                         String methodName,
                         String descriptor,
                         int constantPoolIndex)

Creates an invokedynamic call site descriptor.

Parameters:

bootstrapMethodIndex - index into the BootstrapMethods attribute

methodName - the invoked name of the call site

descriptor - the call site's method descriptor

constantPoolIndex - index of the entry in the constant pool

Method Detail

getBootstrapMethodIndex

public int getBootstrapMethodIndex()

Returns:

the bootstrap method index

getMethodName

public String getMethodName()

Returns:

the method name

getDescriptor

public String getDescriptor()

Returns:

the descriptor

getConstantPoolIndex

public int getConstantPoolIndex()

Returns:

the constant pool index

getParameterSlots

public int getParameterSlots()

Counts the local-variable slots consumed by the parameters.

Returns:

the total slot count, with long and double counting as two

getParameterCount

public int getParameterCount()

Counts the parameters declared in the descriptor.

Returns:

the number of parameters, or 0 for a missing or malformed descriptor

getReturnType

public String getReturnType()

Extracts the return type from the descriptor.

Returns:

the return type descriptor, or "V" if it cannot be parsed

isVoidReturn

public boolean isVoidReturn()

Checks whether the call site returns void.

Returns:

true if the return type is "V"

isLambdaMetafactory

public boolean isLambdaMetafactory()

Checks whether the invoked name matches a common functional-interface method, indicating a LambdaMetafactory call site.

Returns:

true if the name is a known functional-interface method name

isStringConcat

public boolean isStringConcat()

Checks whether this is a StringConcatFactory call site.

Returns:

true if the invoked name is makeConcat or makeConcatWithConstants

toString

public String toString()

Overrides:

toString in class Object
