                                    int[] offsets,
                                    int offset)

compareTo

public int compareTo(Object o)

指定者：

接口 Comparable 中的 compareTo

equals

public boolean equals(Object o)

覆盖：

类 Object 中的 equals

hashCode

public int hashCode()

覆盖：

类 Object 中的 hashCode

getConstant

public Constant getConstant()

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

指定者：

接口 IBinaryField 中的 getConstant

返回：

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

getGenericSignature

Answer the receiver's signature which describes the parameter & return types as specified in section 4.4.4 of the Java 2 VM spec.

指定者：

接口 IBinaryField 中的 getGenericSignature

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

指定者：

接口 IGenericField 中的 getModifiers

返回：

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

指定者：

接口 IBinaryField 中的 getTypeName

返回：

the annotations or null if there is none.

getWrappedConstantValue

public Object getWrappedConstantValue()

Return a wrapper that contains the constant of the field.

返回：

java.lang.Object

hasConstant

public boolean hasConstant()

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

返回：

boolean

initialize

protected void initialize()

This method is used to fully initialize the contents of the receiver. All methodinfos, fields infos will be therefore fully initialized and we can get rid of the bytes.

isSynthetic

public boolean isSynthetic()

Return true if the field is a synthetic field, false otherwise.

返回：

boolean

sizeInBytes

public int sizeInBytes()

Answer the size of the receiver in bytes.
