# Interface StringEntry

All Superinterfaces:
  `ConstantValueEntry, LoadableConstantEntry, PoolEntry`

public sealed interface StringEntry extends ConstantValueEntry
Models a `CONSTANT_String_info` structure, or a string constant, in the constant pool of a `class` file.

The use of a `StringEntry` is represented by a `String`. Conversions are through `ConstantPoolBuilder.stringEntry(String)` and `stringValue()`.

A string entry is composite:

    StringEntry(Utf8Entry utf8)

See Java Virtual Machine Specification:
  4.4.3 The `CONSTANT_String_info` Structure

## Method Summary

Modifier and Type
Method
Description
`boolean`
`equalsString(String value)`
Returns whether this entry describes the same string as the provided string.
`String`
`stringValue()`
Returns the string value for this entry.
`Utf8Entry`
`utf8()`
Returns the UTF constant pool entry describing the string contents.

### Methods declared in interface ConstantValueEntry

`constantValue`

### Methods declared in interface LoadableConstantEntry

`typeKind`

### Methods declared in interface PoolEntry

`constantPool, index, tag, width`

## Method Details

### utf8

Utf8Entry utf8()
Returns the UTF constant pool entry describing the string contents.

Returns:
  the UTF constant pool entry describing the string contents
See Also:
  - `ConstantPoolBuilder.stringEntry(Utf8Entry)`

### stringValue

String stringValue()
Returns the string value for this entry.

API Note:
  A `Utf8Entry` can be used directly as a `CharSequence` if `String` functionalities are not strictly desired. If only string equivalence is desired, `equalsString` should be used. Reduction of string processing can significantly improve `class` file reading performance.
Returns:
  the string value for this entry
See Also:
  - `ConstantPoolBuilder.stringEntry(String)`

### equalsString

boolean equalsString(String value)
Returns whether this entry describes the same string as the provided string.

Parameters:
  `value` - the string to compare to
Returns:
  whether this entry describes the same string as the provided string
