public abstract static class ValueDecoderFactory.DecoderBase
extends TypedValueDecoder

There are some things common to all textual decoders (like white space trimming).

Method Detail

getType

public abstract String getType()

handleEmptyValue

public void handleEmptyValue()

Method called if the value to decode does not contain any non-white space characters (including the case where typed accessor is called for an empty element).

Specified by:

handleEmptyValue in class TypedValueDecoder

verifyDigits

protected void verifyDigits(String lexical,
                            int start,
                            int end)

Method called to check that remaining String consists of zero or more digits

verifyDigits

protected void verifyDigits(char[] lexical,
                            int start,
                            int end,
                            int ptr)

skipSignAndZeroes

protected int skipSignAndZeroes(String lexical,
                                char ch,
                                boolean hasSign,
                                int end)

Returns:

Numeric value of the first non-zero character (or, in case of a zero value, zero)

skipSignAndZeroes

protected int skipSignAndZeroes(char[] lexical,
                                char ch,
                                boolean hasSign,
                                int start,
                                int end)

parseInt

protected static final int parseInt(char[] digitChars,
                                    int start,
                                    int end)

Fast method for parsing integers that are known to fit into regular 32-bit signed int type. This means that length is between 1 and 9 digits (inclusive)

Returns:

Parsed integer value
