Uses of ValueRange in dev.frostlake.executor

Methods in dev.frostlake.executor that return ValueRange

Modifier and Type	Method	Description
ValueRange	QueryExecutor.columnValueRange(Table owner, String columnName)	A catalog column's statistics: the interval between the least and the greatest value in the WHOLE table — every row, whatever the query's WHERE keeps — which is what the account tags the column by, and whether any row holds a NULL, which decides whether the column may answer one.
ValueRange	ExpressionEvaluator.inferStaticRange(Expression expression)	The interval expression's values lie in, as the account's statistics would bound it, or null when none can be known.

Methods in dev.frostlake.executor with parameters of type ValueRange

Modifier and Type	Method	Description
static String	SystemTypeOfDescription.of(DataType declared, String typeText, ValueRange range, boolean predicate)	The description for an argument of declared type whose values lie in range.
static String	SignedStorageWidth.tagOfRange(ValueRange range, int scale)	The tag for every value of an interval once shifted to scale: the wider of its two ends, which is how the account tags a column — by its statistics, never by the row in hand.

Uses of ValueRange in dev.frostlake.executor.expressions

Methods in dev.frostlake.executor.expressions that return ValueRange

Modifier and Type	Method	Description
ValueRange	ExpressionEvaluatorVisitor.inferStaticRange(Expression expr)	The interval expr's values lie in, or null when none can be known.

Uses of ValueRange in dev.frostlake.metastore.model

Methods in dev.frostlake.metastore.model that return ValueRange

Modifier and Type	Method	Description
ValueRange	TableColumn.getValueRange()

Methods in dev.frostlake.metastore.model with parameters of type ValueRange

Modifier and Type	Method	Description
void	TableColumn.setValueRange(ValueRange valueRange)

Uses of ValueRange in dev.frostlake.storage

Methods in dev.frostlake.storage that return ValueRange

Modifier and Type	Method	Description
ValueRange	ResultSetColumn.getValueRange()	The interval this column's values lie in, or null when none is known.

Constructors in dev.frostlake.storage with parameters of type ValueRange

Modifier	Constructor	Description
	ResultSetColumn(String name, DataType dataType, String tableName, DataType staticType, boolean nullable, boolean nullabilityKnown, ValueRange valueRange)
	ResultSetColumn(String name, DataType dataType, String tableName, DataType staticType, boolean nullable, boolean nullabilityKnown, ValueRange valueRange, DataType spelledNumber)

Uses of ValueRange in dev.frostlake.values

Fields in dev.frostlake.values declared as ValueRange

Modifier and Type	Field	Description
static final ValueRange	ValueRange.EMPTY	No value at all: a NULL, or a column that holds nothing.
static final ValueRange	ValueRange.WIDEST	Wider than any tag tells apart, for a plan that always accumulates in sixteen bytes.

Methods in dev.frostlake.values that return ValueRange

Modifier and Type	Method	Description
ValueRange	ValueRange.abs()
ValueRange	ValueRange.add(ValueRange other)
static ValueRange	ValueRange.between(BigDecimal a, BigDecimal b)	The interval between two bounds, in either order, holding no NULL.
ValueRange	ValueRange.including(BigDecimal value)	This interval widened to hold value; a null value widens nothing.
ValueRange	ValueRange.multiply(ValueRange other)	The interval of every product of one value from each side: the four corners bound it.
ValueRange	ValueRange.negate()
static ValueRange	ValueRange.of(BigDecimal value)	The interval of one known value, which is never NULL, or EMPTY for null.
ValueRange	ValueRange.opaqueToConditions()	This interval, as one no condition is settled by; EMPTY stays itself.
ValueRange	ValueRange.scaledBy(BigDecimal factor)	Both bounds multiplied by a non-negative factor.
ValueRange	ValueRange.subtract(ValueRange other)
ValueRange	ValueRange.symmetric()	The interval mirrored about zero, so it holds every value of either sign this one can reach.
ValueRange	ValueRange.union(ValueRange other)	The smallest interval holding both, NULL-able where either side is and opaque to conditions where either side is.
ValueRange	ValueRange.withConditionOpacityOf(ValueRange source)	This interval, opaque to conditions where source is: for a value derived from it.
ValueRange	ValueRange.withNullable(boolean mayBeNull)	This interval, saying whether the expression may also answer NULL; EMPTY stays itself.

Methods in dev.frostlake.values with parameters of type ValueRange

Modifier and Type	Method	Description
ValueRange	ValueRange.add(ValueRange other)
Boolean	ValueRange.below(ValueRange other, boolean orEqual)	Whether every value of this interval lies below every value of other — or at most, with orEqual: TRUE when every pair does, FALSE when none does, null when the intervals leave it open or either is empty.
Boolean	ValueRange.equalTo(ValueRange other)	Whether this interval's values equal other's: TRUE for one shared point, FALSE when the two are disjoint, null when they leave it open or either is empty.
ValueRange	ValueRange.multiply(ValueRange other)	The interval of every product of one value from each side: the four corners bound it.
ValueRange	ValueRange.subtract(ValueRange other)
ValueRange	ValueRange.union(ValueRange other)	The smallest interval holding both, NULL-able where either side is and opaque to conditions where either side is.
ValueRange	ValueRange.withConditionOpacityOf(ValueRange source)	This interval, opaque to conditions where source is: for a value derived from it.
