Constructor Detail

ConstantDynamic

public ConstantDynamic(String name,
                       String descriptor,
                       Handle bootstrapMethod,
                       Object... bootstrapMethodArguments)

Constructs a new ConstantDynamic.

Parameters:

name - the constant name (can be arbitrary).

descriptor - the constant type (must be a field descriptor).

bootstrapMethod - the bootstrap method to use to compute the constant value at runtime.

bootstrapMethodArguments - the arguments to pass to the bootstrap method, in order to compute the constant value at runtime.

Method Detail

getName

public String getName()

Returns the name of this constant.

Returns:

the name of this constant.

getDescriptor

public String getDescriptor()

Returns the type of this constant.

Returns:

the type of this constant, as a field descriptor.

getBootstrapMethod

public Handle getBootstrapMethod()

Returns the bootstrap method used to compute the value of this constant.

Returns:

the bootstrap method used to compute the value of this constant.

getBootstrapMethodArgumentCount
