public static FieldInfo createField(byte[] classFileBytes,
 int[] offsets,
 int offset,
 long version)

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getConstant

public Constant getConstant()

Return the constant of the field. Return org.eclipse.jdt.internal.compiler.impl.Constant.NotAConstant if there is none.

Specified by:

getConstant in interface IBinaryField

Returns:

org.eclipse.jdt.internal.compiler.impl.Constant

getGenericSignature

public char[] getGenericSignature()

Description copied from interface: IBinaryField

Answer the receiver's FieldSignature, which describes the field's type as specified in "4.7.9.1 Signatures" of the Java SE 8 VM spec.

Specified by:

getGenericSignature in interface IBinaryField

getModifiers

public int getModifiers()

Answer an int whose bits are set according the access constants defined by the VM spec. Set the AccDeprecated and AccSynthetic bits if necessary

Specified by:

getModifiers in interface IGenericField

Returns:

int

getName

public char[] getName()

Answer the name of the field.

Specified by:

getName in interface IBinaryField

Returns:

char[]

getTagBits

public long getTagBits()

Description copied from interface: IBinaryField

Answer the tagbits set according to the bits for annotations.

Specified by:

getTagBits in interface IBinaryField

getTypeName

public char[] getTypeName()

Answer the resolved name of the receiver's type in the class file format as specified in section 4.3.2 of the Java 2 VM spec. For example: - java.lang.String is Ljava/lang/String; - an int is I - a 2 dimensional array of strings is [[Ljava/lang/String; - an array of floats is [F

Specified by:

getTypeName in interface IBinaryField

Returns:

getAnnotations

public IBinaryAnnotation[] getAnnotations()

Description copied from interface: IBinaryField

Answer the runtime visible and invisible annotations for this field or null if none.

java.lang.Object

hasConstant

public boolean hasConstant()

Return true if the field has a constant value attribute, false otherwise.
