Class Definitions

java.lang.Object

manifold.preprocessor.definitions.Definitions

public class Definitions
extends java.lang.Object

Models definitions as a hierarchy of maps. Searches for a definition in leaf-first order where the leaf definitions are controlled by the #define and #undef directives in the compiling source file. Parent definitions correspond with the following:

• build.properties files in the source file's directory ancestry
• Custom compiler arguments provided by the -Akey[=value] javac command line option
• Compiler and JVM environment settings such as Java source version, JPMS mode, operating system, etc.

Note the effects of #define and #undef are limited to the file scope. This means #define definitions are not available to other files. Similarly, parent definitions masked with #undef are not affected in other files.

clear

public void clear()

isDefined

public boolean isDefined(java.lang.String def)

Returns:

True if there a definition having name def, regardless of its value.

getValue

public java.lang.String getValue(java.lang.String def)

define

public java.lang.String define(java.lang.String def)

Define def in the source file's local definition space.

define

public java.lang.String define(java.lang.String def,
                               java.lang.String value)

Define def in the source file's local definition space with value.

undef

public java.lang.String undef(java.lang.String def)

Remove def from the File's local definition space. Note if def is defined in a parent scope e.g., a properties file, it remains defined. In other words #undef applies exclusively to the source file scope.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
