Method Details

getDeclaringType

public Type getDeclaringType()

Description copied from interface: Field

Gets the complex type or list type that declared this field.

The declaring type may differ from the complex type owning this field.

For example, in the case of a derived complex type, the field is owned by both the derived type and the base type, but it's declared only by the base type.

Specified by:

getDeclaringType in interface Field

Returns:

the complex that declared this field

getName

public QName getName()

Description copied from interface: Field

Gets the field name.

Specified by:

getName in interface Field

Returns:

the field name

getType

public Type getType()

Description copied from interface: Field

Gets the field type.

Specified by:

getType in interface Field

Returns:

the field type

getDefaultValue

public Object getDefaultValue()

Description copied from interface: Field

Gets this field default value or null if none.

Specified by:

getDefaultValue in interface Field

Returns:

the default value if any was specified, null otherwise

isNillable

public boolean isNillable()

Description copied from interface: Field

Checks whether this field is nillable (can have null values).

Specified by:

isNillable in interface Field

Returns:

true if the field can have null values

isConstant

public boolean isConstant()

Description copied from interface: Field

Checks whether this field is constant (is read only).

Specified by:

isConstant in interface Field

Returns:

true if the field is constant false otherwise

setDefaultValue

public void setDefaultValue(String value)

Description copied from interface: Field

Sets the default value of this field.

Specified by:

setDefaultValue in interface Field

Parameters:

value - the value to set

setNillable

public void setNillable(boolean isNillable)

Description copied from interface: Field

Sets the nillable flag.

Specified by:

setNillable in interface Field

setConstant

public void setConstant(boolean isConstant)

Description copied from interface: Field

Sets the constant flag.

Specified by:

setConstant in interface Field

getMaxOccurs

public int getMaxOccurs()

Description copied from interface: Field

Gets the maximum number this field may occurs in the owner type.

By default this is 1. -1 is returned if not a maximum limit is imposed.

Specified by:

getMaxOccurs in interface Field

Returns:

the max occurrences

getMinOccurs

public int getMinOccurs()

Description copied from interface: Field

Gets the minimum number this field may occurs in the owner type.

By default this is 1.

Specified by:

getMinOccurs in interface Field

Returns:

the min occurrences

setMaxOccurs

public void setMaxOccurs(int max)

Description copied from interface: Field

Sets max number of occurrences for this field.

Specified by:

setMaxOccurs in interface Field

Parameters:

max - max number of occurrences
