Method Detail

testSchemaMerge

public void testSchemaMerge()

testStringToNumberConversion

public void testStringToNumberConversion()

Test the standard string-to-type conversion using an ad-hoc conversion from the input type (the type used by the row set builder) to the output (vector) type.

testNumberToStringConversion

public void testNumberToStringConversion()

Test the standard string-to-type conversion using an ad-hoc conversion from the input type (the type used by the row set builder) to the output (vector) type.

testStringToNumberConversionError

public void testStringToNumberConversionError()

dec

public static BigDecimal dec(int value)

testImplicitConversion

public void testImplicitConversion()

Tests the implicit conversions provided by the column writer itself. No conversion mechanism is needed in this case.

testImplicitConversionIntTruncation

public void testImplicitConversionIntTruncation()

The column accessors provide only int setters. For performance, the int value is assumed to be of the correct range for the target column. If not, truncation of the highest bytes occurs.

The assumption is, if the reader or other code expects that overflow might occur, that code should be implemented in the client (or in a type conversion shim), leaving the normal code path to optimize for the 99% of the cases where the value is in the proper range.

testImplicitConversionIntOverflow

public void testImplicitConversionIntOverflow()

Overflow from double-to-int is detected.

testImplicitConversionDoubleClamp

public void testImplicitConversionDoubleClamp()

Implicit conversion from double (or float) follows the Java Math.round rules: round to the closest long value. Readers that want other behavior should insert a type-conversion shim to implement the preferred rules.

testStringToInterval

public void testStringToInterval()

Implicit conversion from String to period using default ISO format.

testIntervalToString

public void testIntervalToString()

testStringToDateTimeDefault

public void testStringToDateTimeDefault()

Test VARCHAR to DATE, TIME and TIMESTAMP conversion using default ISO formats.

testStringToDateTimeCustom

public void testStringToDateTimeCustom()

testDateTimeToString

public void testDateTimeToString()

testBooleanToFromString

public void testBooleanToFromString()

Test conversion to/from Java-style Booleans.

testDecimalFromString

public void testDecimalFromString()

testDecimalOverflow

public void testDecimalOverflow()

testBasicConversionType

public void testBasicConversionType()

Test the conversion type for a subset of type pairs.

testSpecialConversionType

public void testSpecialConversionType()

Test the specialized types: conversation to/from string.

testBlankOptions

public void testBlankOptions()

Test the properties for how to handle blanks on string-to-number conversions.
