OpenJDK 27 · java.lang.classfile.BootstrapMethodEntry

Models an entry in the bootstrap method table. The bootstrap method table is stored in the BootstrapMethods attribute, but is modeled by the ConstantPool, since the bootstrap method table is logically part of the constant pool.

A bootstrap method entry is composite:

BootstrapMethodEntry(
    MethodHandleEntry bootstrapMethod,
    List<LoadableConstantEntry> arguments
)

Method Summary

Modifier and Type	Method and Description
public List<LoadableConstantEntry>	Returns: the bootstrap arguments arguments() Returns the bootstrap arguments.
public MethodHandleEntry	Returns: the bootstrap method bootstrapMethod() Returns the bootstrap method.
public int	Returns: the index into the bootstrap method table corresponding to this entry bsmIndex() Returns the index into the bootstrap method table corresponding to this entry.
public ConstantPool	Returns: the constant pool associated with this entry constantPool() Returns the constant pool associated with this entry.

constantPool back to summary

constantPool	back to summary
public ConstantPool constantPool() Returns the constant pool associated with this entry. API Note Given a `ConstantPoolBuilder` `builder` and a `BootstrapMethodEntry` `entry`, use `builder.canWriteDirect(entry.constantPool())` instead of object equality of the constant pool to determine if an entry is compatible. Returns:ConstantPool the constant pool associated with this entry

public ConstantPool constantPool()

Returns the constant pool associated with this entry.
