Known Direct Implementers
jdk.internal.classfile.impl.AbstractPoolEntry.FloatEntryImpl
Imports
java.lang.classfile.TypeKind, jdk.internal.classfile.impl.AbstractPoolEntry
Models a CONSTANT_Float_info structure, or a float constant, in the constant pool of a class file.

The use of a FloatEntry is modeled by a float. Conversions are through ConstantPoolBuilder#floatEntry and floatValue(). In the conversions, all NaN values of the float may or may not be collapsed into a single "canonical" NaN value.
