Class FieldTypeDefinition

  • All Implemented Interfaces:
    Serializable
    public class FieldTypeDefinition
extends Object
implements Serializable
    INTERNAL: Purpose: Define a database platform specific definition for a platform independent Java class type. This is used for the field creation within a table creation statement.

    Responsibilities:

    • Store a default size and know if the size option is required or optional.
    • Store the name of the real database type.
    • Maintain maximum precision and optionall min & max Scale.

    • Method Detail

      • getDefaultSize

        public int getDefaultSize()
        Return the default size for this type. This default size will be used if the database requires specification of a size, and the table definition did not provide one.

      • getDefaultSubSize

        public int getDefaultSubSize()
        Return the default sub-size for this type. This default size will be used if the database requires specification of a size, and the table definition did not provide one.

      • getMaxPrecision

        public int getMaxPrecision()

      • getMaxScale

        public int getMaxScale()

      • getMinScale

        public int getMinScale()

      • getName

        public String getName()
        Return the name. Can be any database primitive type name, this name will then be mapped to the Java primitive type, the database type varies by platform and the mappings can be found in the subclasses of DatabasePlatform. these Java names and their ODBC mappings include; - Integer -> SQL_INT - Float -> SQL_FLOAT - Double -> SQL_DOUBLE - Long -> SQL_LONG - Short -> SQL_INT - BigDecimal -> SQL_NUMERIC - BigInteger -> SQL_NUMERIC - String -> SQL_VARCHAR - Array -> BLOB - Character[] -> SQL_CHAR - Boolean -> SQL_BOOL - Text -> CLOB - Date -> SQL_DATE - Time -> SQL_TIME - Timestamp -> SQL_TIMESTAMP

      • getTypesuffix

        public String getTypesuffix()
        Returns a type suffix (like unicode, byte or ascii) for maxdb create table stmts

      • isSizeAllowed

        public boolean isSizeAllowed()
        Return if this type can support a size specification.

      • isSizeRequired

        public boolean isSizeRequired()
        Return if this type must have a size specification.

      • shouldAllowNull

        public boolean shouldAllowNull()

        Set the default size for this type. This default size will be used if the database requires specification of a size, and the table definition did not provide one.

      • setDefaultSubSize

        public void setDefaultSubSize​(int defaultSubSize)
        Set the default sub-size for this type. This default size will be used if the database requires specification of a size, and the table definition did not provide one.

      • setIsSizeAllowed

        public void setIsSizeAllowed​(boolean aBoolean)
        Set if this type can support a size specification.

      • setIsSizeRequired

        public void setIsSizeRequired​(boolean aBoolean)
        Set if this type must have a size specification.

      • setShouldAllowNull

        public void setShouldAllowNull​(boolean allowsNull)
        Set if this type is allowed to be null for this platform

      • setLimits

        public FieldTypeDefinition setLimits​(int maxPrecision,
                                     int minScale,
                                     int maxScale)
        Set the maximum precision and the minimum and maximum scale.
        Returns:
        this Allowing the method to be invoked inline with constructor
