clone
Description copied from interface:Spatial
Creates a copy of this Spatial object with different id. -
getId
public long getId()Description copied from interface:Spatial
Get id of this Spatial object -
isNull
public boolean isNull()Description copied from interface:Spatial
Test whether this object has no value -
toString
-
hashCode
public int hashCode() -
equals
Description copied from class:Value
Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00. -
compareTypeSafe
Description copied from class:Value
Compare this value against another value given that the values are of the same data type.- Specified by:
compareTypeSafe
in classValue
- Parameters:
v
- the other valuemode
- the compare modeprovider
- the cast information provider- Returns:
- 0 if both values are equal, -1 if the other value is smaller, and 1 otherwise
-
equalsIgnoringId
Check whether two objects are equals, but do not compare the id fields.- Specified by:
equalsIgnoringId
in interfaceSpatial
- Parameters:
o
- the other key- Returns:
- true if the contents are the same
-
getSQL
Description copied from interface:HasSQL
Appends the SQL statement of this object to the specified builder. -
getType
Description copied from interface:Typed
Returns the data type. -
getValueType
public int getValueType()Description copied from class:Value
Get the value type.- Specified by:
getValueType
in classValue
- Returns:
- the value type
-
