Enum Constant Summary

Enum Constants

Enum Constant and Description
DOUBLE_COLON Treat expressions containing a double-colon delimiter as special, encoding the entire content into the key.
ESCAPES Support standard escape sequences in plain text and default value fields, which begin with a backslash ("\") character.
GENERAL_EXPANSION Support Policy file style "general" expansion alternate expression syntax.
LENIENT_SYNTAX Ignore syntax problems instead of throwing an exception.
MINI_EXPRS Support single-character expressions that can be interpreted without wrapping in curly braces.
NO_RECURSE_DEFAULT Do not support recursion in default values.
NO_RECURSE_KEY Do not support recursive expression expansion in the key part of the expression.
NO_SMART_BRACES Do not support smart braces.
NO_TRIM Do not trim leading and trailing whitespace off of the expression string before parsing it.

Enum Constant Detail

NO_TRIM

public static final Expression.Flag NO_TRIM

Do not trim leading and trailing whitespace off of the expression string before parsing it.

LENIENT_SYNTAX

public static final Expression.Flag LENIENT_SYNTAX

Ignore syntax problems instead of throwing an exception.

MINI_EXPRS

public static final Expression.Flag MINI_EXPRS

Support single-character expressions that can be interpreted without wrapping in curly braces.

NO_RECURSE_KEY

public static final Expression.Flag NO_RECURSE_KEY

Do not support recursive expression expansion in the key part of the expression.

NO_RECURSE_DEFAULT

public static final Expression.Flag NO_RECURSE_DEFAULT

Do not support recursion in default values.

NO_SMART_BRACES

public static final Expression.Flag NO_SMART_BRACES

Do not support smart braces.

GENERAL_EXPANSION

public static final Expression.Flag GENERAL_EXPANSION

Support Policy file style "general" expansion alternate expression syntax. "Smart" braces will only work if the opening brace is not the first character in the expression key.

ESCAPES

public static final Expression.Flag ESCAPES

Support standard escape sequences in plain text and default value fields, which begin with a backslash ("\") character.

DOUBLE_COLON

public static final Expression.Flag DOUBLE_COLON

Treat expressions containing a double-colon delimiter as special, encoding the entire content into the key.

Method Detail

values

public static Expression.Flag[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Expression.Flag c : Expression.Flag.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Expression.Flag valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
