Function

public Function()

方法详细资料

accept

public void accept(ExpressionVisitor expressionVisitor)

指定者:

accept 在接口中 Expression

getName

public String getName()

getMultipartName

public List<String> getMultipartName()

setName

public void setName(String string)

withName

public Function withName(String name)

setName

public void setName(List<String> string)

isAllColumns

public boolean isAllColumns()

setAllColumns

public void setAllColumns(boolean b)

isIgnoreNulls

public boolean isIgnoreNulls()

setIgnoreNulls

public void setIgnoreNulls(boolean ignoreNulls)

This is at the moment only necessary for AnalyticExpression initialization and not for normal functions. Therefore there is no deparsing for it for normal functions.

isDistinct

public boolean isDistinct()

true if the function is "distinct"

返回:

true if the function is "distinct"

setDistinct

public void setDistinct(boolean b)

isUnique

public boolean isUnique()

true if the function is "unique"

返回:

true if the function is "unique"

setUnique

public void setUnique(boolean b)

getParameters

public ExpressionList getParameters()

The list of parameters of the function (if any, else null) If the parameter is "*", allColumns is set to true

返回:

the list of parameters of the function (if any, else null)

setParameters

public void setParameters(ExpressionList list)

getNamedParameters

public NamedExpressionList getNamedParameters()

the parameters might be named parameters, e.g. substring('foobar' from 2 for 3)

返回:

the list of named parameters of the function (if any, else null)

setNamedParameters

public void setNamedParameters(NamedExpressionList list)

isEscaped

public boolean isEscaped()

Return true if it's in the form "{fn function_body() }"

返回:

true if it's java-escaped

setEscaped

public void setEscaped(boolean isEscaped)

getAttribute
