ABSTRACT
SINGLE bean attribute information
DESCRIPTION
PerlBean::Attribute::Single contains SINGLE bean attribute information. It is a subclass of PerlBean::Attribute. The code and documentation methods are implemented.
CONSTRUCTOR
- new (OPT_HASH_REF)
-
Creates a new
PerlBean::Attribute::Singleobject.OPT_HASH_REFis a hash reference used to pass initialization options.OPT_HASH_REFis mandatory. On error an exceptionError::Simpleis thrown.Options for
OPT_HASH_REFmay include:allow_empty-
Passed to "setAllowEmpty ()". Defaults to 1.

METHODS
- getOverloadedAttribute ()
-
This method is inherited from package
'PerlBean::Attribute'. Searches superclass packages for an identically namedPerlBean::Attribute. If found it is returned otherwiseundefis returned - getPackage ()
-
This method is inherited from package
'PerlBean::Attribute'. Returns the package name. The package name is obtained from thePerlBeanto which thePerlBean::Attributebelongs. Or, if thePerlBean::Attributedoes not belong to aPerlBean,mainis returned. - getPackageUS ()
-
This method is inherited from package
'PerlBean::Attribute'. CallsgetPackage ()and replaces:+with C <_>. - type ()
-
This method is inherited from package
'PerlBean::Attribute'. Determins and returns the type of the attribute. The type is eitherBOOLEAN,SINGLEorMULTI. - writeAllowIsa (FILEHANDLE)
-
Writes
%ALLOW_ISAline for the attribute.FILEHANDLEis anIO::Handleobject. - writeAllowRef (FILEHANDLE)
-
Writes
%ALLOW_REFline for the attribute.FILEHANDLEis anIO::Handleobject. - writeAllowRx (FILEHANDLE)
-
Writes
%ALLOW_RXline for the attribute.FILEHANDLEis anIO::Handleobject. - writeAllowValue (FILEHANDLE)
-
Writes
%ALLOW_VALUEline for the attribute.FILEHANDLEis anIO::Handleobject. - writeDefaultValue (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes%DEFAULT_VALUEline for the attribute.FILEHANDLEis anIO::Handleobject. - writeDocClauses (FILEHANDLE)
-
This method is inherited from package
'PerlBean::Attribute'. Writes documentation for the clauses to which the contents the contents of the attribute must adhere.FILEHANDLEis anIO::Handleobject. - writeDocInheritMethods (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes documentation for the access methods for the attribute in the case the attibute methods are inherited.FILEHANDLEis anIO::Handleobject. - writeDocInit (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes documentation for_initialize ()for the attribute.FILEHANDLEis anIO::Handleobject. - writeDocMethods (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes documentation for the access methods for the attribute.FILEHANDLEis anIO::Handleobject. - writeMethods (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes the access methods for the attribute.FILEHANDLEis anIO::Handleobject. - writeOptInit (FILEHANDLE)
-
This method is an implementation from package
'PerlBean::Attribute'. Writes_initialize ()option parsing code for the attribute.FILEHANDLEis anIO::Handleobject. - setAllowEmpty (VALUE)
-
State that the attribute is allowed to be empty.
VALUEis the value. Default value at initialization is1. On error an exceptionError::Simpleis thrown. - isAllowEmpty ()
-
Returns whether the attribute is allowed to be empty or not.
- setAllowIsa (ARRAY)
-
Set the list of allowed classes absolutely.
ARRAYis the list value. Each element in the list is allowed to occur only once. Multiple occurences of the same element yield in the last occuring element to be inserted and the rest to be ignored. On error an exceptionError::Simpleis thrown. - addAllowIsa (ARRAY)
-
Add additional values on the list of allowed classes.
ARRAYis the list value. The addition may not yield to multiple identical elements in the list. Hence, multiple occurences of the same element cause the last occurence to be inserted. On error an exceptionError::Simpleis thrown. - deleteAllowIsa (ARRAY)
-
Delete elements from the list of allowed classes. Returns the number of deleted elements. On error an exception
Error::Simpleis thrown. - existsAllowIsa (ARRAY)
-
Returns the count of items in
ARRAYthat are in the list of allowed classes. - valuesAllowIsa ()
-
Returns an
ARRAYcontaining all values of the list of allowed classes. - setAllowRef (ARRAY)
-
Set the list of allowed references absolutely.
ARRAYis the list value. Each element in the list is allowed to occur only once. Multiple occurences of the same element yield in the last occuring element to be inserted and the rest to be ignored. On error an exceptionError::Simpleis thrown. - addAllowRef (ARRAY)
-
Add additional values on the list of allowed references.
