Pack200.IPacker.ClassAttributePfx Field

Definition

When concatenated with a class attribute name, indicates the format of that attribute, using the layout language specified in the JSR 200 specification.

[Android.Runtime.Register("CLASS_ATTRIBUTE_PFX")]
public const string ClassAttributePfx;
[<Android.Runtime.Register("CLASS_ATTRIBUTE_PFX")>]
val mutable ClassAttributePfx : string

Field Value

Attributes

Remarks

When concatenated with a class attribute name, indicates the format of that attribute, using the layout language specified in the JSR 200 specification.

For example, the effect of this option is built in: pack.class.attribute.SourceFile=RUH.

The special strings #ERROR, #STRIP, and #PASS are also allowed, with the same meaning as #UNKNOWN_ATTRIBUTE. This provides a way for users to request that specific attributes be refused, stripped, or passed bitwise (with no class compression).

Code like this might be used to support attributes for JCOV:

<code>
                Map p = packer.properties();
                p.put(CODE_ATTRIBUTE_PFX+"CoverageTable",       "NH[PHHII]");
                p.put(CODE_ATTRIBUTE_PFX+"CharacterRangeTable", "NH[PHPOHIIH]");
                p.put(CLASS_ATTRIBUTE_PFX+"SourceID",           "RUH");
                p.put(CLASS_ATTRIBUTE_PFX+"CompilationID",      "RUH");
</code>

Code like this might be used to strip debugging attributes:

<code>
                Map p = packer.properties();
                p.put(CODE_ATTRIBUTE_PFX+"LineNumberTable",    STRIP);
                p.put(CODE_ATTRIBUTE_PFX+"LocalVariableTable", STRIP);
                p.put(CLASS_ATTRIBUTE_PFX+"SourceFile",        STRIP);
</code>
