getMaxLength()
public long getMaxLength()
Optional. Maximum length of values of this field for STRINGS or BYTES.
If max_length is not specified, no maximum length constraint is imposed
on this field.
If type = "STRING", then max_length represents the maximum UTF-8
length of strings in this field.
If type = "BYTES", then max_length represents the maximum number of
bytes in this field.
It is invalid to set this field if type is not "STRING" or "BYTES".

getParserForType()
public Parser<TableFieldSchema> getParserForType()
Overrides
getPrecision()
public long getPrecision()
Optional. Precision (maximum number of total digits in base 10) and scale
(maximum number of digits in the fractional part in base 10) constraints
for values of this field for NUMERIC or BIGNUMERIC.
It is invalid to set precision or scale if type is not "NUMERIC" or
"BIGNUMERIC".
If precision and scale are not specified, no value range constraint is
imposed on this field insofar as values are permitted by the type.
Values of this NUMERIC or BIGNUMERIC field must be in this range when:
- Precision (P) and scale (S) are specified:
[-10^(P-S) + 10^(-S), 10^(P-S) - 10^(-S)]
- Precision (P) is specified but not scale (and thus scale is
interpreted to be equal to zero):
[-10^P + 1, 10^P - 1].
Acceptable values for precision and scale if both are specified:
- If type = "NUMERIC":
1 <= precision - scale <= 29 and 0 <= scale <= 9.
- If type = "BIGNUMERIC":
1 <= precision - scale <= 38 and 0 <= scale <= 38.
Acceptable values for precision if only precision is specified but not
scale (and thus scale is interpreted to be equal to zero):
- If type = "NUMERIC": 1 <= precision <= 29.
- If type = "BIGNUMERIC": 1 <= precision <= 38.
If scale is specified but not precision, then it is invalid.
int64 precision = 8 [(.google.api.field_behavior) = OPTIONAL];
| Returns |
|---|
| Type | Description |
long | The precision.
|
getScale()
Optional. See documentation for precision.
int64 scale = 9 [(.google.api.field_behavior) = OPTIONAL];
| Returns |
|---|
| Type | Description |
long | The scale.
|
getSerializedSize()
public int getSerializedSize()
| Returns |
