OpenJDK 27 · java.lang.classfile.constantpool.DynamicConstantPoolEntry

Superinterface modeling dynamically-computed constant pool entries, which include ConstantDynamicEntry and InvokeDynamicEntry, in the constant pool of a class file.

Different types of dynamically-computed constant pool entries bear structural similarities, but they appear in distinct locations. As a result, their uses are represented by different symbolic descriptors, specific to each subtype.

A dynamic constant entry is composite:

DynamicConstantPoolEntry(
    BootstrapMethodEntry bootstrap,
    NameAndTypeEntry nameAndType
)

bootstrapMethodIndex back to summary

bootstrapMethodIndex	back to summary
public int bootstrapMethodIndex() Returns index of the entry in the bootstrap method table for this constant. The return value is equivalent to `bootstrap().bsmIndex()`. Returns:int index of the entry in the bootstrap method table for this constant

public int bootstrapMethodIndex()

public default Utf8Entry name()

Returns the name indicated by this symbolic reference.

Returns:Utf8Entry: the name indicated by this symbolic reference

nameAndType back to summary

nameAndType	back to summary
public NameAndTypeEntry nameAndType() Returns the name and the descriptor string indicated by this symbolic reference. Returns:NameAndTypeEntry the name and the descriptor string indicated by this symbolic reference See Also `Execution of bootstrap methods`, `ConstantPoolBuilder::constantDynamicEntry(BootstrapMethodEntry, NameAndTypeEntry)`, `ConstantPoolBuilder::invokeDynamicEntry(BootstrapMethodEntry, NameAndTypeEntry)`

public NameAndTypeEntry nameAndType()

Returns the name and the descriptor string indicated by this symbolic reference.

Returns:NameAndTypeEntry: the name and the descriptor string indicated by this symbolic reference
See Also: Execution of bootstrap methods, ConstantPoolBuilder::constantDynamicEntry(BootstrapMethodEntry, NameAndTypeEntry), ConstantPoolBuilder::invokeDynamicEntry(BootstrapMethodEntry, NameAndTypeEntry)

type back to summary

type	back to summary
public default Utf8Entry type() Returns the descriptor string indicated by this symbolic reference. This is a field descriptor string if this entry is a `ConstantDynamicEntry`, or a method descriptor string if this entry is a `InvokeDynamicEntry`. API Note Each subinterface has its specific accessor named `typeSymbol` for the symbolic descriptor derived from this descriptor string. Returns:Utf8Entry the descriptor string indicated by this symbolic reference

public default Utf8Entry type()

Returns the descriptor string indicated by this symbolic reference. This is a field descriptor string if this entry is a ConstantDynamicEntry, or a method descriptor string if this entry is a InvokeDynamicEntry.

API Note

Each subinterface has its specific accessor named typeSymbol for the symbolic descriptor derived from this descriptor string.

Returns:Utf8Entry: the descriptor string indicated by this symbolic reference
