Constructor Detail

StringLengthConstraint

public StringLengthConstraint(int length)

Constructs a maxlength constraint of the specified length.

Parameters:

length - the max string length

StringLengthConstraint

public StringLengthConstraint(int length,
                              String type)

Constructs a maxlength constraint of the specified length.

Parameters:

length - the max string length

StringLengthConstraint

public StringLengthConstraint(RelationalOperator operator,
                              int length)

Constructs a string length constraint with the specified operator and length constraint.

Parameters:

operator - the operator (one of ==, >, >=, <, <=)

length - the length constraint

StringLengthConstraint

public StringLengthConstraint(RelationalOperator operator,
                              int length,
                              String type)

Constructs a string length constraint with the specified operator and length constraint.

Parameters:

operator - the operator (one of ==, >, >=, <, <=)

length - the length constraint

type - Type used to resolve messages.

StringLengthConstraint

public StringLengthConstraint(int min,
                              int max)

Constructs a string length range constraint.

Parameters:

min - The minimum edge of the range

max - the maximum edge of the range
